Blue light of 475nm is incident normally on a 30-60-90 prism as shown in the picture. Among the many refracted and reflected rays in this setup the reflected ray on Face 2 is depicted. The prism has an index of refraction of 1.5 and lies on water as shown (index of refraction of water = 1.33). (a) Determine the wavelength of the light inside the prism. (b) Determine the angle of refraction of the refracted ray (if any) on Face 2. (c) Determine the angle of refraction of the refracted ray (if any) on Face 3. (d) If the prism lies on a different liquid, what is the biggest index of refraction that the liquid could have such that no there's no refracted ray at Face 2.
